I've seen a lot of approaches to crashing. I thought maybe even most of them. I innovated a new one today.

Here it is, as near as I can tell.

As I was giving a hard kick over the top of a hill to try to catch a rider ahead of me, somehow, the torque on the cassette pulled the wheel out of the dropout. It jammed itself into the stays on the left. Being out of the saddle at the time, I was not expecting for the rear wheel to lock up. For a brief moment, I thought I could save it. But I went down hard. I cracked my helmet and got a curious assortment of road rash, featuring at least four distinct patches on my left knee. On the bike, I'm out a wheel, a saddle, and bar tape, and maybe some cables.

Does anyone know how something like this could happen? I'm not a mechanical expert, but I've never heard of a rear wheel coming out of position before.

Yes, the QR was closed tight.
